If you let Adam LaRoche walk, you have to be prepared to bring in a quality CF (move Bryce to LF)
Why? Why can't we leave Harper in center and bring in a power hitting leftfielder?
But either way it just begs the question, why bother? On one hand: let LaRoche walk, move Morse to First, acquire an outfielder. On the other hand, stay with what you have. In the first case we give up something valuable, in the second case we don't, and either way we end up about the same. So why bother? Why not keep it the way it is.
